Abstract

Hinged segment switches, in particular for a suspended monorail system, are formed from a switch point (3) and two connecting rails (9, 10). A segmented tongue, formed from a number of tongue members (5 - 8) which are each arranged jointedly one behind the other and can swivel about an axis of rotation, can be assigned to either one of the two connecting rails. In this arrangement, a first connecting member (5) of the segmented tongue is connected rotatably with the switch point (3) and a last, free closing member (8) is connected, so that it can swivel at least between the connection rails, with a guide means define. To define exactly the angular position of the closing member with respect to the connecting member and to associate it more exactly with the respective connecting rails so that a rail vehicle can pass over without problems, the guide means for the closing member comprises a curved link (25) to make it possible to determine exactly the closing position for the connecting rails. <IMAGE>

Description

The invention relates to a switch, in particular for a monorail, with a switch tip and two connecting rails, with a link tongue which can be assigned to either of the two connecting rails and which is formed from a number of tongue links arranged in an articulated manner one behind the other and pivotable about an axis of rotation, a first connecting link Link tongue rotatably hinged to the turnout tip and a last, free closing member for pivoting is connected to a guide at least between the connecting rails.

Monorails are used as conveyor systems e.g. used in the automotive industry. Body parts, motors, etc. can be transported along rails with the help of carriages running on rollers. The rails are usually located some distance from the floor on the ceiling and the vehicle parts hang on the vehicles of the monorail below the rails.

Branches of the rails, in particular switches, are required to vary the conveying path.

So far, sliding points have mainly been used. In this embodiment there are two rail sections, e.g. an arc and a straight line, which are brought into the respective switch position by moving a movable inner frame.

The construction is complex and requires high precision. Each track section also requires a separate busbar feed. The external dimensions of this type of switch are very large because the laterally displaceable rail pieces each require considerable space to the right or left of the monorail.

In a tongue switch according to FR-PS 2 387 319 known according to the preamble of patent claim 1, a solid, small frame is sufficient. Instead of arches and straight lines, a splint that is broken up into tongue links is used. The tongue members form a straight line or a polygon curve in the respectively possible end positions of the tongue switch. The tongue switch is pivotally connected to the switch tip and its free end can be pivoted between the respective connecting rails by means of an adjustment drive.

A disadvantage of this switch is that its free end, the closing member, is guided in a straight line along a frame. An exact closed position can only be achieved with at most one connecting rail. Since the connecting rails are arranged at an angle to one another and possibly at a different distance from the point of the switch, the closing element cannot be brought up to the second connecting rail in an optimal angular position along a linear guide.

The invention is therefore based on the object to provide a tongue switch of the type mentioned with a simple structure with regard to an improved angular position relative to the respective connecting rails with an optimal guide.

This object is achieved with a tongue switch with the features of the preamble of claim 1 in that for the exact determination of the closed position in the connecting rails, the guide of the closing member comprises an arcuate link.

The precise guidance of the closing element is thus advantageously possible. The guide guarantees the exact angular position where alignment to the fixed connecting rail is required. In this way, there is a safe passage from the link tongue to the connecting rails. This extends the service life of the rail and wagon and ensures trouble-free operation. In a favorable embodiment of the arch backdrop, it is designed as a guide slot in a plate. Depending on the design of the switch, the guide slot is easily e.g. can be produced by milling in the plate. In another embodiment, the curved link can also be designed as a correspondingly curved flat steel instead of a guide slot. In this case, the closing member can be guided along the arc link by guide rollers acting on the flat steel on both sides.

In this context, it is furthermore favorable if the arch backdrop extends above the tongue switch at least between the connecting rails. A rail vehicle is not hindered during its movement along the tongue switch due to the curved backdrop. Since the arched backdrop extends into the area of the connecting rails, there is precise alignment and adaptation with respect to the closing member and the connecting rails. Of course, it is also possible to arrange the arch backdrop below the tongue switch or on both sides. It is also possible to form the arch backdrop extending beyond the connecting rail.

In particular, it proves to be advantageous if stops are formed on adjacent tongue members and / or on or in the axis of rotation in order to limit the pivoting angle in each case. In this way, adjacent elements can only be pivoted relative to one another at a predetermined angle and the tongue switch can be deflected up to a maximum curvature. Larger kinks between two adjacent tongue members, which could lead to a malfunction during transport, are excluded. Likewise, he is the guide of the reed switch between the connecting rails easier, since the tongue members support each other.

In an advantageous embodiment of the invention, at least one stop lever is arranged on the respective axis of rotation connecting the tongue members, which is fixed relative to one tongue member and can be pivoted between two stops relative to the other tongue member. It is thus easily possible to determine the swivel angle by appropriately designing the stop lever when the stops are held. The stop lever can be designed so that the pivot angle can be adjusted subsequently by bending the lever.

In a simple embodiment, a side wall of the tongue member and / or a bracket arranged on this wall are designed as stops for the stop lever. In this way, only an additional bracket is required, which can be carried out in the simplest way. The swivel angle can be varied by exchanging the bracket.

Tongue switches, e.g. have a longitudinal or a rightward curvature in the closed positions, it is advantageous if the wall in the area of the stop lever has an opening corresponding to this as a lever passage and brackets designed as stops are arranged on both sides of the wall. For example, the maximum swivel angle for both curvatures is set with a stop lever.

In another embodiment, stop levers projecting on both sides of the axis of rotation essentially in the direction of travel and corresponding stops are formed on both sides. So you get a simple assignment of the stop lever and associated tongue member. Excessive deflection of the tongue members among one another is not possible.

In order to vary the swivel angle even without replacing the stirrups, it is advantageous if the spacer stirrups can be varied from the wall of the tongue member by actuators. As a result, the swivel angle can be precisely adjusted in a particularly simple manner.

Furthermore, it is advantageous if the stop lever is designed to lie flat against the stops. In this way, any forces that occur in the stop positions can be better transmitted than in the case of a point-like or linear concern.

In a favorable embodiment, the closing member is connected to a guide arm that runs outside the outer contour of a rail vehicle traveling on this tongue member and can be moved along the arc link. In this context, it is particularly favorable if the guide arm is essentially U-shaped and is detachably fastened in a side wall of the tongue member with the aid of a support leg and is movably mounted on the arc link by means of a guide leg. An exact and trouble-free guidance is possible. In addition, the arc link and the locking member are directly assigned to each other with the help of the guide arm.

To switch between the respective end positions in connection with the connecting rails, it is particularly advantageous if the guide leg can be moved along the arc link by an adjusting device. The drive is e.g. Crank drives, pneumatic cylinders or others can be used. Appropriate clutches or sliding hubs can simultaneously prevent overloading in the actuator.

In order to align the closing member in the rail direction in the closed position with the connecting rails, it is advantageous if the curved link is designed as a straight guide at its ends that define the end position of the guide leg. The arch backdrop is not necessarily formed in a continuous arch, but can also have arch sections of different curvature. Branches are also possible, e.g. can be used for the tongue switch parking positions.

As an additional device for determining the end positions for the guides of the guide leg along the arc link, it is advantageous if these end positions are determined by end stops arranged on the actuating device. These can also be designed to be adjustable for fine adjustment of the end positions.

In order to make it easier to drive over the tongue switch along the tongue members, it is advantageous if at least at one end of the side wall of the tongue members there are support rails which run in the direction of travel and overlap in the travel area. The overlap ensures that no gaps open between the individual tongue members during the pivoting process of the tongue switch, which gaps have to be overrun by the guide rollers and would have a considerable influence on the service life of the guide rollers.

In order to ensure safe driving along the tongue members, it is advantageous if the tongue members have an essentially double-T-shaped cross section, the upper side of a T-bar being designed as a support rail and the sides of the T-bar as guide surfaces. In this way, guide and idler rollers can roll seamlessly from one tongue link to the other in the overlap area.

In order to achieve a mutual pivoting of adjacent tongue members in the overlapping area in a simple manner, it is favorable to if in the overlap area the tongue members are formed at least in sections along the axis of rotation with mutually complementary curvatures. This applies in particular to adjacent T-beams, at the top and bottom of the double-T-shaped cross section of the tongue members, while the side walls of the tongue members are plate-shaped and are arranged at a distance from one another. The complementary curvatures are in engagement with one another and can be rotated into one another.

In an advantageous embodiment, the sections are convexly or concavely curved, and in the convex sections, a joint bore that is coaxial with the axis of rotation is formed for mounting a joint pin. The convex and concave sections interlock and are pivotable about the hinge pin.

In order to achieve a larger swivel angle, it is advantageous if the curved sections are essentially semicircular in the direction of the axis of rotation, the concave sections having a larger radius of curvature than the convex sections. Due to the circular design, adjacent tongue members can be easily rotated against each other, the angle of rotation being determined by the radii of curvature of concave and convex sections.

So that it is possible to run over along the side faces of the T-beams, it is advantageous if the radius of the convex sections essentially corresponds to half the width of the tongue member.

In this context, too, it is advantageous if the concave sections are designed to be aligned in the direction of travel with the outer surfaces of the tongue members. This makes it possible to drive over from concave to convex sections with almost no gap formation. The carrying or guide rollers roll over the tongue links almost seamlessly.

In order to ensure simple assembly of the tongue members to form a tongue switch, end regions of a tongue member lying in the direction of travel can be complementary to one another. This makes it possible to form the entire tongue switch with a uniform tongue member. Ends assigned to each other are put together overlapping and rotatably connected by a hinge pin.

For easier rotatability, the joint bore can have a coaxial bearing bore at least in one end region for receiving a ball bearing.

In order to facilitate the connection of the switch to the switch tip, it is advantageous if the switch tip is designed to be complementary to an end region of the connecting member at its end connected to the switch. Corresponding to the connection of the individual tongue members, the connection to the turnout tip can also be established.

In order to facilitate an assignment of the locking member and connecting rails in the closed position of the tongue switch, it is advantageous if the locking member has at its free end for the positive connection to the connecting rails a connecting end running at right angles to the direction of travel in one plane.

In order to facilitate the power supply of a rail vehicle, it is possible if a number of conductor lines running in the direction of travel are arranged on one side on the side wall of the tongue members for power supply. This means that cables outside the rail are not required.

In order to rule out any interference with the live conductor lines during use, it is advantageous if the conductor lines are arranged in essentially U-shaped insulating strips. This prevents a short circuit or accidental contact with the power lines.

In order to ensure a continuous power supply during the swiveling process, it is advantageous if the conductor lines have a smaller width compared to the U-web in order to be freely movable in the insulating strips. In this context, it is also advantageous if the insulating strips are interrupted in the region of the axes of rotation and the conductor lines are designed to be continuous. In this way, the insulating strips can also be made from a material which is not very elastic.

If the insulating strips are brought close to the axis of rotation, it is advantageous if the ends of the insulating strips in the region of the axes of rotation are inclined towards each other in the direction of the side wall of the tongue member.

In order to ensure precise alignment and assignment of the closing element and the corresponding connecting rail, it is expedient if stop stops are formed at least in the region of the guide arm of the guide arm to determine the end positions of the closing element and are assigned to the guide leg.

In an advantageous embodiment, the stop stops for adjusting the end position in the direction of movement of the guide leg are variable in length. In this way, fixed stop stops can be changed for fine adjustment.

As a passage between the connection during the swiveling of the switch rails and turnout tip is not possible, it is advantageous if a safety lock is arranged at least in the region of the connecting rails to lock a rail section that has not been released. If a rail vehicle approaches the switch during the swiveling process, it will be stopped at this safety lock at the latest. The connection is only released again when the connection between a connecting rail and the turnout tip is established.

In this context, it is advantageous if the security lock is pivotally mounted. It is thus possible in a simple manner to move the security lock back and forth between a release position and a securing position.

In an advantageous embodiment, the safety lock is formed from a plate which extends substantially perpendicular to the direction of travel and is arranged above the connecting rails and which can be pivoted upward by engagement of the guide arm to release the respective connecting rail. An electrical or other control of the safety lock with the aid of additional devices is unnecessary since the guide arm intervenes directly on the safety lock.

In order to pivot the safety lock in a simple manner when the guide arm moves, it is advantageous if a lifting arm formed perpendicular to the guide bracket of the guide arm is arranged on the latter. When the guide arm moves along the arc, the respective safety lock is raised in the end positions of the tongue switch using this lifting arm.

In order to make lifting easier and to ensure that the link tongue is only released when the closed position is reached, it is advantageous if the safety lock has a ramp-shaped attachment assigned to the lifting arm. As a result, the safety lock can be lifted without great effort due to the ramp-shaped design of its approach. At the same time, the tongue switch is gradually released.

In order at the same time to prevent the tongue switch from being driven from the direction of the switch tip during the pivoting process, it is advantageous if a plate-shaped fixed lock is arranged above the tongue members between the connecting rails. A rail vehicle that moves along the switch in the direction of the connecting rails is stopped in this way in front of the closing member.

In order to obtain a flat surface as possible in the closed positions of the tongue switch, it is advantageous if the stop stop is designed to act on the lifting arm of the guide arm perpendicular to the direction of travel and to the lifting arm. A stop stop is assigned to each connecting rail, which ensures a positive locking position of the tongue switch and connecting rail.

In order to assemble the tongue switch quickly and easily, it is advantageous if it is arranged on a support frame which is designed in particular for attachment to ceiling beams of buildings. It is also advantageous if the support frame is designed to form a right or left switch. The corresponding devices such as stop stops, safety locks, fixed locks, etc., as well as the necessary fastening devices for the tongue switch, switch tip and connecting rails are designed twice in the support frame for quick conversion between a right and a left switch.

It is also possible to use e.g. to form a Y-turnout or a three-way turnout.

In order to facilitate the manufacture of the individual tongue members, it is advantageous if the tongue members are made from cast parts. These are designed so that they can be joined together at their ends without mechanical processing. Only the bearing bores into which the ball bearings are inserted or which receive the hinge pin are subsequently machined. The end piece of the switch tip or the closing member can also be produced in a simple manner from the castings. They can be produced by sawing off an unnecessary end part of a tongue member.

In order to be able to install the tongue links in both directions, it is advantageous if the insulating strips and conductor rails can optionally be laid on one side wall of the tongue links. The guide arm is then placed on the corresponding opposite side wall. A fixed installation direction of the individual tongue members is not specified in this way.

The invention is explained and described below with reference to exemplary embodiments shown in the drawing.

In Fig. 1 the tongue switch 1 is shown in plan view. It has a frame 2 which consists of an essentially rectangular part and a trapezoidal part adjoining a longer rectangular side. Along the free rectangular side of the frame 2 there is a tongue switch formed from link elements 5, 6, 7 and 8. At the turnout tip 3, the connecting member 5 of the tongue turnout is rotatably connected to the turnout tip end 4 by means of a joint 41. The turnout tip end 4 and the turnout tip 3 are fastened with the aid of a carrier 11 along a shorter rectangular side of the frame 2. An extension rail 9 is arranged on the opposite, shorter side of the rectangle with the aid of a carrier 12. The tongue switch formed from link elements 5, 6, 7 and 8 connects the switch tip end 4 and the extension rail 9 in a straight line.

The locking member 8 of the switch is positively arranged in the closed position to the connecting rail 9. The link elements 5, 6, 7 and 8 can be pivoted into the positions 5 ', 6', 7 'and 8' with the aid of the guide arm 13, which is arranged perpendicular to the closing element 8 and is connected to it essentially centrally. In the pivoted position, the closing member 8 'is arranged in a form-fitting manner with respect to a second connecting rail 10. The tongue members 7', 6 'and 5' are connected between the closing member 8 'and the point tip 4 in the form of a polygon. All link elements are connected to one another via the axes of rotation 41 and 42 corresponding axes of rotation. The guide arm 13 can be moved along an arc link 25 with the aid of an adjusting device 15, 17 and 20. An actuating lever 15 connects the guide arm 13 to a rotary plate 17 which can be pivoted about an axis 21 in directions 16 by means of a drive 20. The adjusting lever 15 is rotatably mounted both on the rotary plate 17 and on the lifting arm 13 via connecting devices 14 and 22.

The connecting device 14 connecting the actuating lever 15 to the guide arms 13 engages in the arc link 25 for guiding the guide arm 13. The guide arm 13 can be moved along this backdrop to the position 13 '.

A lifting arm 30 projecting on both sides is arranged perpendicular to the guide arm 13 at the height above the direction 14. In plan view, it has an essentially rectangular cross section. In the position shown here, lifting arm 30 runs essentially parallel to the rail direction of closing element 8. On one side of guide arm 13, lifting arm 30 lies flush against stop 23. In the position of the holding arm identified by 13 ', the lifting arm 30 bears against the stop 24 corresponding to the stop 23.

The end of the lifting arm 30 opposite the stops 23 and 24 is arranged below the ramps 35 and 36, respectively. These run essentially perpendicular to the lifting arm 30 and are formed on safety locks 28 and 29, respectively. They run parallel to securing plates 31 and 34, respectively, which support them. These are pivotably mounted on swivel devices 32 and 33 arranged on the frame 2. The end of the securing plates 31 and 34 opposite the pivoting devices is e.g. in the case of the securing plate 31, it can be moved along two guides 38 arranged on both sides, essentially perpendicular to the securing plate 31. The guides 38 delimit a slot in which the securing plate 31 can be raised or lowered. The guides 38 are fastened to the frame 2 with the aid of a connecting plate 37.

On one side of the guide 38, a retaining lug 40 is formed essentially perpendicular to it. A holding lug 39 formed on the pivotable end of the securing plate 31 comprises the guide 38 and can be put down on the holding attachment 40.

The security lock 29 is designed in accordance with the security lock 28 with guides, retaining attachment and retaining lug.

Corresponding to the stop 23 for the lifting arm 30, a stop 18 is arranged on the rotary plate 17. When rotating about axis 21 along direction 16, the rotating plate 17 can be pivoted into position 17 '. In this position, it bears against a stop 19 corresponding to the stop 24 for the lifting arm 30.

A fixed lock 26, 27 is arranged on the frame 2 between the rail members 7 and 7 '. It is formed from an essentially rectangular mounting plate 27 and a locking plate 26 arranged perpendicular to it. This extends essentially between the outer contours of the tongue members 7 and 7 '. 2, the arched backdrop 25 is shown enlarged. It is designed as a slot in a substantially rectangular backdrop plate. In its middle part it is delimited by circular lines 43 and 44. The rounded end regions 46 and 48 adjoin the respective circular lines at a bend and are designed as straight guides.

In Fig. 3 the tongue switch from Fig. 1 is shown in a side plan view.

The frame 2 has an elongated U-shape. Brackets 11 and 12 are arranged thereon parallel to the downwardly pointing U-legs. They are fastened at the end opposite the frame 2 by means of essentially square fastening plates 49 and 51 on the point tip end 4 and on the connecting rail 9. In each of the 4 corners of the fastening plates 49 and 51, a bore 50 and 52 is formed for the passage of fastening screws.

Likewise, the guide arm 13 is fastened to the locking member 8 with a fastening plate 53 and corresponding bores or screws 54.

At the end of the guide arm 13 opposite the closing member 8, the lifting arm 30, which is essentially rectangular in cross section, is formed perpendicular to the latter. The lifting arm 30 is arranged below the ramp 35 at one end. This has an essentially square cross section and is arranged along the securing plate 31. In this illustration, the end of the securing plate 31 arranged between the guides 38 is arranged above the lifting arm 30 at a distance from the latter.

The guides 38 are surrounded on one side in the direction of the lifting arm 30 by a retaining lug 39 arranged on the securing plate 31. At the lower end of the guides 38 a retaining lug 40 corresponding to the retaining lug is formed on one side.

On the side of the lifting arm 30 opposite the safety lock 28, a stop 23 fastened to the frame 2 is arranged. This extends perpendicular to the lifting arm 30, a screw 55 being arranged at its end opposite the frame 2 at the level of the lifting arm 30.

The guide arm 13 is connected to the rotary plate 17 via the adjusting lever 15 running perpendicularly to this. The rotating plate 17 can be rotated about the screw 21 with the aid of the drive 20. A U-shaped bracket 45 is arranged between drive 20 and frame 2. One leg runs essentially parallel to the frame 2, while the opposite leg runs along the drive 20 and is fastened to it by means of screw 21.

4, the guide arm 13 is shown enlarged.

Again, parts that have already been shown in FIGS. 1 to 3 are provided with the same reference numbers.

The guide arm 13 has an essentially U-shaped cross section, the holding leg 56 having a greater width than the guide leg 57. Both legs run parallel to each other. At the end of the holding leg 56, the mounting plate 53 is arranged. This runs essentially parallel to the closing element 8. The closing element 8 is fastened to the fastening plate 53 with the aid of screws 54. Perpendicular to the mounting plate 53, cross-sectionally rectangular rail supports 58 and 59 are arranged symmetrically to the upper and lower ends of the closing element 8. In an extension of the closing member 8 in the direction of the guide leg 57 is arranged on this lifting arm 30. Above the lifting arm 30, the ramp 35 connected to the securing plate 31 is arranged on it. The securing plate 31 can be raised from the position 31 ′ by the ramp 35 facing the guide leg 37. With the frame 2 arranged above the securing plate 31, it is pivotally connected by means of the bearing 32. At the end of the securing plate 31 opposite this bearing 32, two guides 38 pointing in the direction of the guide bracket 57 are arranged from the frame. Lift arm 30 is arranged at a short distance from the guides 38. The securing plate 31 can be moved up and down between these. Corresponding to the positions of the securing plate identified by 31 and 31 ', the retaining lug is shown in positions 39 and 39'. It is designed to be slidable along the guide 38 and includes it. In position 39 ', the retaining lug rests on the retaining projection 40 formed on the guides 36.

In Fig. 5 the connection of two tongue members 5 and 6 is shown. Both tongue members can be pivoted relative to one another about axis of rotation 42. A hinge pin 60 is arranged between tongue member 5 and 6 concentric to the axis of rotation. In the middle of the tongue members and the hinge pin 60, two substantially rectangular stop levers are formed symmetrically to the axis of rotation 42. The stop lever-receiving openings 62 and 61 are arranged in both tongue members. These are also formed symmetrically to the axis of rotation 42.

A rectangular bracket 66 running parallel to the axis of rotation 42 is arranged on the tongue member 6. This extends over the opening 61 and the stop lever 64, with it essentially running with an outer edge along the side of the stop lever 64 facing away from the axis of rotation 42. Screws 67 and 68 are arranged in the bracket 66 directly above the opening 61.

On the rail member 5, a bracket 65 is arranged on the opposite side. This has two bores 71 and 72 each under or above the opening 62 and two further bores 69 and 70 within the opening. All four openings lie on a line parallel to the axis of rotation 42. The bracket 65 runs parallel to the bracket 66 and essentially has dimensions corresponding to this.

6 shows a section along the line VI-VI of FIG. 5. The stop lever 63 runs in the direction of the tongue member 5 and is connected to it by a bracket 65 and a screw 64. The bracket 65 rests on both the stop lever 63 and the tongue member 5.

The stop lever 64 extends at an angle to the stop lever 63 and points away from the tongue member 6. The stop lever 64 rests on the bracket 66 with a beveled end running in the direction of the bracket 66. The stop lever 64 is connected to the stop lever 63 through the hinge pin 60 by a weld 101. In the area of these welded parts, it is displaced approximately half a width in relation to the stop lever 63 in the direction of the bracket 66.

In Fig. 7, a tongue member 5 is shown in plan view and side elevation. The tongue member is formed from a horizontal support rail 76 and a wall 75 arranged perpendicular to it and running centrally to this. The support rail 76 has different bores at the opposite ends. The left end 77 is essentially semicircular. A bore 78 with the radius R is formed concentrically with this circular end and the axis of rotation 79. The bore is made along the wall 75 into the bottom part 90 corresponding to the support rail 96.

A concave curved recess 80 is formed in the support rail 76 below the end piece 77. This extends symmetrically to the wall 75 between the corner points 84 and 85 arranged on the outer surface of the support rail 76. The concave recess 80 has a larger radius of curvature than the circular end piece 77. The curvature in the corner points 84 and 85 runs in the direction of the tangents 81 and 82. Between the axis 83 perpendicular to the axis of rotation 79 and the corner points 84 and 85, end piece 77 runs straight in the direction of the outer sides of the support rail 76. A corresponding concave recess is formed in the bottom part 90. The other end of the tongue member 5 is complementary to the circular end portion 77 or the concave recess 88. A concave recess 87 is formed on the upper side of the support rail 76. This has a radius of curvature corresponding to the concave recess 80. The height of the circular end part 77 and the concave formation 87 correspond. A circular end piece 86 is formed below this. This has a radius corresponding to the radius of the end piece 77. A stepped bore 102 is formed concentrically with the end piece 86 and with the axis of rotation 89. The step 88 within the bore 102 is formed in the immediate vicinity of the wall 75. The distance from wall 75 to the axis of rotation 89 is A and corresponds to the radius R of the bore 78.

The connection of two tongue members will be briefly described below in connection with FIG. 7. Since the tongue members are all of the same design, an overlap in the end regions is easily possible. The circular end part 77 of a second tongue member is pushed onto the concave recess 87. At the same time, the concave recess 80 comes into contact with the circular end part 86. Before that, a ball bearing must be arranged on the step 88 in the stepped bores 102 in the support rail 76 and in the bottom part 90. This has an inner bore with radius R for receiving a hinge pin. A hinge pin is inserted into the bore 78 through a first ball bearing, along the wall 75, concentrically to the axis of rotation 89, through a second ball bearing in the base part 90 and through a second bore 78.

After the hinge pin has been fastened, the adjacent tongue members can then be pivoted about the axis of rotation 89. Due to the larger radius of curvature of the concave recesses, the adjacent tongue members can be pivoted relative to one another in the direction of the tangents 81 and 82.

8 and 9, the connecting member 4 and the closing member 8 are shown, which are connected in a corresponding manner to the tongue switch.

In Fig. 8, the connector 4 has a flat end 91. This runs perpendicular to the wall 94 and has recesses 92 and 93 for connection to the point of the switch. The support rail 95 has an end part already described in FIG. 7 on the end opposite the flat end 91. Correspondingly, a concave recess 87 is arranged above the circular end part 86. The stepped bore 102 is formed concentrically to the axis of rotation 89 both in the support rail 95 and in the base part 96. The distance from the wall part 94 to the axis of rotation 89 is, as in FIG. 7A, and corresponds to the radius R of the circular bore 78 from FIG. 7 for receiving the hinge pin.

9 shows the closing element 8. This has a perpendicular to the wall 98 end, flat end 100. The end of the closing element 8 opposite this end corresponds to the circular end part 77 from FIG. 7.

10 to 13, a selection of different types of turnouts is shown with the link tongue according to the invention.

In Fig. 10 a discharge switch 103 is shown in the right version. By pivoting the link tongue formed from the link elements 5, 6, 7 and 8 by the angle 104, the connection between the turnout tip 3 and the extension rails 9 and 10 can be established. This embodiment of a switch essentially corresponds to the switch shown in FIG. 1.

11 shows a feed-in switch 105 in the left-hand version. Along the rail elements 9 and 10, which serve as entry rails into the switch, it is possible to introduce vehicles via the switch tip end 4 onto the switch tip 3 via the sectional switch switch formed from the link elements 5, 6, 7 and 8. In order to establish the connection between the entry rails 9 and 10 and the turnout tip 3, the link tongue can be pivoted through the angle 106 between these two.

10 and 11, the link tongue for pivoting is in each case formed between a linear arrangement and an arrangement pivoted by the angle 104 or 106, in FIG. 12 this is to form a Y-switch 107 by the angle 108 pivotable between two extension rails 109 and 110 arranged at an angle to the switch tip 3. All elements for guiding the tongue and fixing it in the end positions can also be used with switch 107. The frame 2 from FIG. 1 can also be used for receiving the switch with the corresponding safety locks 29 and 31 for the Y switch 107.

The same also applies to the 3-angle switch 111 according to FIG. 13. With this switch, the link tongue can be pivoted by 2 through the angle 112 between 2 extension rails 115 and 116 arranged at an angle to the switch tip 3, and also an impact rail 114 at approximately that half pivot angle 112 is arranged. The turnout tip 3 and the drop rail 114 are arranged linearly in this case. Such a switch 111 corresponds essentially to the discharge switch from FIG. 10, which is designed both in the right-hand version and in the left-hand version. In this case, a frame 2 can be produced by mirror-image doubling along the link elements 5, 6, 7, 8 from FIG. 1.

Of course, the soft 107 from FIGS. 12 and 111 from FIG. 13, which are shown as transfer switches, can also be designed as corresponding transfer switches.
